DOUBLE-POINTED REPRODUCING -STYLUS FOR TALKING-MACHINES, AND HOLDER THEREFOR.

Specification of Letters Patent.

Patented Dec.2,1913.

Application filed September 30, 1912. Serial No. 723,012.

To all whom it may concern.

Be it known that I, EDWARD T. CoNDoN, J12, a citizen of the United States, and a resident of New York, in. the county of New Yorkand State of New York, have invented certain new' and useful Improvementsin Double-Pointed Reproducing-Styli for Talking-Machines, and Holders Therefor, of which the following is a specification.

The invention relates to a novel reproducing stylus or phonographic needle as employed in connection with rotating cylinders or disks in talking machines, and to a novel holder therefor.

The invention has for its object to provide a one-piece reversible stylus having oppositely pointed ends, one of which may be of different character from the other if desired; and, it has for a further object to suitably protect the inactive end of such stylus.

The nature of the invention will best be understood when described in connection with the accompanying drawings, in which- Figure 1 is a front elevation of a sound box, stylus holder, partly in section, and the stylus held thereby. Fig. 2 is a view of the underside thereof. Figs. 3 and 4 are respectively a plan and elevation of a guard for the stylus. Figs. 5 and 6 are respectively a plan and elevation of another form of ard.

Similar characters of reference designate 7 corresponding parts throughout the several views.

Referring-t0 the drawing, lO designates the sound box of a talking machine and to which is attached in well-known manner the arm or holder 11 for the stylus 12 employed in such machines. This arm is hollow throughout'its central portion, which is designed to receive the stylus 12, the latter being held therein in well-known manner by means of a set screw 13.

The stylus ordinarily employed is pointed only at one end which engages the record, the other being cut off flat and bottoming in the said arm 11. In making the stylus pointed at both ends, as shown, the life of the same is doubled; and, moreover, modifications in the tone may be obtained by providing points of different characteristics. As shownin Fig. 1, the point 14 is made more blunt than the point 15 of the reproducing stylus 12, whereby the tones reproduced by the former are am lified.

In employing a needle 0 the aforesaid? character, it becomes necessary to adequatel protect the end, which for the time being is not to engage bottoms in t e arm 11.

If no such means the record, and which end were provided, the bottoming point wouldi generally be damaged and rendered unfit for use due to scraping of the same on th bot'-' tom of the arm in tightening the stylus in position therein. To obviate this difficulty, a guard piece 16, Figs. 3 and 4, slightly tapered as shown, may be forced into the arm 11. This guard piece conforms to the shape of the central hollow portion of the said arm and is provided, furthermore, with a slot 17 extendin inwardly from one of the corners thereof and adapted to receive the pointed and temporarily inactive end of the stylus 12. The slot tapers slightly from-' top to bottom so that the stylus may be firmly bottomed against said guard, which is, furthermore, provided with a recess 18'111 its underface to accommodate the portion of the point projecting beyond the depthbf the slot. In this manner. points of different taper may be readily accommodated.

In Figs. 5 and 6, I have illustrated a sonicwhat simpler guard, the same consisting of a pad 5200f soft or resilient, cushioning material such as cork or rubber, adapted to be inserted in the bottom of the arm 11 and" against which the point of the. stylus may be brought.

I claim 1. In a talking machine, the combination with a stylus arm having a socket of sufiicient depth to properly receive and retain the shank and inactive end of a double pointed stylus; of a frictionally held guard therein for the inactive end of the stylus and into which the same is adapted to pass.

2. The combination with a reproducing stylus for talking machines, having oppositely pointcdends; of a holder therefor, and a guard in said holder provided with a slot adapted to receive the temporarily inactive end of the stylus bottoming therein.

3. The, combination with a reproducing stylus fortalking machines, having oppositely pointed ends; of a holder therefor, and a guard at the bottom of said holder a slot 0 receive the tempoi of the stylus bottoming 1 zee in its under face, wrioustupers may be acprovided "w raniy ma the-rem.

a. reproo ucing films, havmg oppo- & holder therefor, provided with a tapering e r.- to receive the temporarily inactiw end 953 the stylus boitoming therein.

5. The combination with a reproducing stylus for talking machines, having oppositely pointed ends; of a holder therefor, and a guard in said hoidez edeoteri to embrace the empomri1y vi of the stylus withoui; contacting the geint thereof.
